DescriptionCertified by LPCB to LPS1175 Issue 8 SR2 or LPS1175 Issue 7 SR3 or SR4 the SecurGuard steel doorset offers a made-to order high quality security rated door for external use on any building requiring higher levels of burglar resistance.
Constructed from Magnelis steel (SR2 only) for the very best corrosion resistance and a 10 year warranty (location dependent) this door offers the best attack resistance and overall door strength. It is also available in the SR2 version with 60 minute fire rating and also with panic hardware for use as an emergency fire exit door.
The SecurGuard range consists of three doors, each with different levels of security.
SR2 has been tested to LPS1175 SR2: Offers up to 3 minutes resisting an opportunist burglar forcing entry of protected premises with various tools such as levers, drills and screwdrivers. Ideal for commercial premises where a greater level of security is required.
SR3, tested to LPS1175 SR3: Offers up to 5 minutes of resistance during a determined break-in of protected premises using tools such as a crow bar, short axe and cordless tools.
The SR3 is ideal for commercial and industrial premises or buildings with a high risk of burglary or maybe the doors are in exposed locations.
SR4, tested to LPS1175 SR4: Offers up to 10 minutes of resistance when undergoing a break-in by a more experienced burglar using tools such as a sledgehammer, power drill and high powered cordless tools.
With the greatest levels of resistance of the SecurGuard range, the SR4 is suitable for applications where there is a significant risk of attack.

MeasureA steel doorset is always ordered by the OVERALL dimensions including the door leaf and outer sub fixing frame with no tolerances allowed for. Most people would generally allow 5mm tolerance all the way around the door, but it all depends on how square or true your aperture is on site.
This means if your structural opening size is measured as 1000mm width and 2100mm height the door and frame ought to be 990mm wide and 2090mm high with the frame and any threshold included.
Always measure the top, middle and bottom of your aperture width and the left and right hand side for the height and if possible do a measure to make sure the opening is square as well.
Always use millimetres for measuring as this is how we relay back the ordering dimensions to you for checking and approving a drawing for your order.
The Robust Tuff-Dor does not have the normal 30mm adjustable fitting frame but does have a 3mm chassis system extension.
